110-70-3, The molecularity of an elementary reaction is the number of molecules that collide during that step in the mechanism. If there is only a single reactant molecule in an elementary reaction, that step is designated as unimolecular.110-70-3, name is N1,N2-Dimethylethane-1,2-diamine. A new synthetic method of this compound is introduced below.
2-(2-methoxyphenyl)-1,3-dimethylimidazolidine. A solution of o-anisaldehyde (9.0 g, 66 mmol) and N,N’-dimethylethylenediamine (7.9 mL, 73 mmol) in ethanol (180 mL) was stirred at r.t. for overnight. MgSO4 (30 g) was added and the mixture was stirred for 20 min. The reaction mixture was filtered and washed with ether. The solvent was removed in vacuo to afford 2-(2-methoxyphenyl)-1,3-dimethylimidazolidine as a light yellow solid, 12 g, yield 88%. 1H NMR (500 MHz, CHLOROFORM-D) delta ppm 2.21 (s, 6H) 2.57-2.72 (m, 2H) 3.34 (d, J=2.75 Hz, 2H) 3.82 (s, 3H) 4.13 (s, 1H) 6.88 (d, J=8.24 Hz, 1H) 7.00 (t, J=7.48 Hz, 1H) 7.25-7.30 (m, 1H) 7.67 (d, J=7.63 Hz, 1H).
There are, however, a few established termolecular elementary reactions. The reaction of nitric oxide with oxygen appears to involve termolecular steps. you can also browse my other articles about N1,N2-Dimethylethane-1,2-diamine, CAS: 110-70-3
